Its highly-integrated design elimi- nates the need for costly external components required by other Ethernet controllers. The CS8900A includes on-chip RAM, 10BASE-T transmit and receive filters, and a direct ISA-Bus interface with 24 mA Drivers. In addition to high integration, the CS8900A offers a broad range of performance features and configuration- options. Its unique PacketPage architecture automatically adapts to changing network traffic pat- terns and available system resources. The result is increased system efficiency. The CS8900A is available in a 100-pin TQFP package ideally suited for small form-factor, cost-sensitive Ether- net applications. With the CS8900A, system engineers can design a complete Ethernet circuit that occupies less than 1.5 square inches (10 sq. cm) of board space.
